ings, the glue is fed to the article by means of discs l0 that are connected to a shaft ll that is driven by a suitable sprocket gear Wheel 12 which isdriven by a sprocket chain 131 that maybe connectedtoa suitable source ot power tor causing rotation ot' the discs 10. The discs l0 are located in the glue pots lei having the covers 15.' Thediscs l() protrude from the bottom off the pots ll, propel' Wiping and glue-retaining devices being provided within thepotstofproducel the proper regulated supply of glue `to-cause the `torinationof a'iilm of glue on the articles oit the desired thickness. l y

The articles are conveyed. by. suitable belts beneath the discs so as to lreceive the Lglue therefrom. i Thestitucture shown inthe drau'iiisfI is l gfned for spreading glue over sheet material, Vsuch as cardboard, and betweenJ predetermined points on the cardboard with respectito the ends of the card-` board.

The cardboard lt'is directed beneath the glue pots and in proximity to the glue'discs byV means of the. belts l? and suitable feed rollers, The cardboard may be supported b'etweenithe belts by any suitable means such as the strips 18 that are-` supported on the bed of the glue machine or any other suitable part ofthe frame of the glue machine. An automatic glue-spread- .ing'regulatorll issupported so as to be engaged by thearticle l@ as it is being' conveyed bythe belt l?.

The; automatic device is siiipported on a board Q1 that is connected to upriglits forming af part ot the `gluev machine, by meansy of threaded rods 23, and secured rl`he rods 253 extend through slots 'i9 whereby the .regulator 2O may be longitudinally adjusted relative to the `:glue machine. A pair of levers-25l and extend to a point below the upper surta-ces: et thebelts 17 and the upper edges ofthe strips 18 and so-as to be .located'in the path ot the end edges of the cardboard 1G. The lever 25 is pivotally connected to an adj ustable 'plate 27 that may be adj'ustably secured to the board 2l by means of the bolts E28 that are located in the slot 29 formed in the plate 2T. The lever 25 isa-lsoconnected to a bar 3l by means of a 'The bar 81 is guided in its longitudinal movements by means of the bracket 36 and the pin 37 that extends through theslot v Slight angular movements of the bai 31 may vbe produced away from the bracket 36 about the pin 37, the slot 34 being such as to permit the pin 32' toV move along the armof the lever 25. Thus the cardboard 16 holds the 'lever `25 in theV position that it is turned by the forward edge of the cardboard and maintains the bar 31 in the position in'which it is moved by the lever 25, while the board passes under the lever 25.

The bar 31 is provided with a notch 40 that is drawn from beneath the pin 41 located on a link 42. The link 42 is connected to the lever 26. The lever 26 is pivoted to the board 21 and when it is operated by theforward edge of the cardboard 16, while the lever 25 is being held in Iits position by thecardboard, the pin 41 engages the forward end of the bar 81`to draw it down about the pin 87. The link 42is malinta-ined in positionvbymeans of the pin 43 which is secured to the board 21 and the `spring 44'tliat is connected to the link 42 and the board 21 to draw the upper end of-l the link 42 towards the forward end of the board 21 and against the pin-'43. Y The pin 43 may be located in a notch formed in the upper end of the link 42 whereby the movement of the link 42 is limited by the length of the notch.

The downward movement of the forward end of the bar 31 is communicated to a shaft 45 supported inthe standards 22 and 46. The bar 81 is connected to the shaft 45. by means of the rod or link 47 and the arm 48 to produce angular or rotative movements,

in the shaft 45. Vhen,l therefore, the rod 47 is pulled downward and the shaft 45 is r giii'en a short angular movement, it causes the outer ends of the arms 49 connected to the shaft 45 to be raised. This movement is communicatedto the levers 50 by means of the rods 51.

The levers 50 are pivotally connected by means of brackets 52 secured tothe bottoms of the glue pots 14. The levers 50 are pivotally supported by means of the shaft53 that extend through the brackets 52. The shafts 53 extend across the bottoms of the glue pots, each lever end of a shaft The other endk of the shaft 58 is connected to a guide 54 that guides the cardboard 16 relative to the discs 10, and rotative movement of the shafts 58.

'produced by the levers 50 raises the cardboard 16 so as to bring an edge portion of the cardboard into contact with the discs to receive the gluefrom the discs.

vThe guide 54 is preferably formed of 50 being located at'one,

position. K

spring 62 which in turn is connected to the jfor receiving the end edge of the cardboard and directing it into the channel. The

guide is provided with a recess 56 located in the upper side of the guide and which extends from the following end of the guide to a point in advance of the shaft 58 and so thatwhen the guide 54 is tilted by the operation of the lever 50, the metal of which the guide is foi'ined will not touch the discs 10. This will avoid the collection of glue on the guidebut it will permit the disc to spread theglue on the cardboard as it 4passes through the guide, when the guide is tilted. Thus when the bar 81 is held in position so that the notch 40 is di'awn from beneath the pin 41 and the forward end ,ofl the bar is pulled down by the operation of the lever 26, the guides 54 will be turned soy as to lift the kedges of the cardboard and cause the film of glue to be spread along edge portions of the cardboard. The controlling device may thus be so located and' thelever may be so adjusted as to cause the gluing operation to start at predetermined desired points along the edges of the cardboard and f until the guides 454 are permitted to dip down to lowervtheedges of .the cardboard away from the discs 10.

The distribution or spread of the glue on the cardboard 16 is discontinued by the guides 54 being tilted downward so as to -move side edge portions of the cardboard.

away from the discs 10. This movement is caused by the following edge of the cardboard 16 passing from beneath the lever 25. The bar 81 is'connected to a spring 58 and thevspring 58 is connected to a pin 59 that is secured to the board 21. The elasticity of the spring 58 draws thebar 31 along the pin 37 and the bracket 36 until the notch 4() is brought intor alignment with the pin 41 located on the link 42, and notwithstanding the fact that the lever 26 is still held in a raised position7 the bar 81 is permitted to swing upwards by the elasticity of the spring 58 until it strikes the pin 60. This raises the rod 47 which causes a return movement of the arm 48 and theshaft 45. This also causes a return movement of the arms 49 and the rods 51. This in turn operates the levers to cause the guides 56 to dip downward. The levers 50 are also connected to springs 61 which coact with the spring 58 to cause the return of the guides 54 to their normal positions. As the cardboard 16'is carried along its following edge passes beneath the lever 26, which permits the lever 26 to return to its normal The link 42 is connected to a board 21. The spring 62 draws the link l2 upward until it is stopped by the pin a3 and also moves the lever 26 to its normal position. Thus the mechanism is set ready to receive the succeeding cardboard. The earboards may be fed through the machine as rapidly as may be desired, each successive cardboard receiving the glue during the desired periods ot' its travel through the guides. The glue thus may be deposited betiveen points more or less spaced from the ends'ol the cardboard, as may be desired. Since the first contact of the cardboard With the discs l0 will deposit glue over a short length, the cessation of the spread of the glue must occur at a very short period in advance ot' the time When the points at the following ends of the glue 'films pass from beneath the discs. This difference in point of time is controlled by the adjustments ot the levers 25 and 26 relative to each other. The distances of the ends of the glue films from the leading and following edges et the cardboard may be controlled or adjusted by the adjustment of the board 2l relative to the supporting rods 23. Thus the glue ilm may be deposited so as to leave end portions or corner portions ot the cardboard free from the glue. They cardboard may then be folded for any purpose desired, such as to form an attractive and strengthened edge, or may be folded into the form ot a box, or other articles or objects may be secured to the cardboard that has received the glue, as may be desired and according to the purpose 'for which the article is to be used. i
